Tornado.Cash is a decentralized privacy protocol for ethereum users that improves privacy and security. It uses cutting edge cryptography to make transactions untraceable and deposit and withdrawal addresses unlinkable. The protocol is based on smart contract, meaning there are no third parties needed and the dangers of human error are reduced. Users deposit ETH and receive a unique cryptographic note for withdrawal later. Privacy is maintained using zero-knowledge proofs. Community governance provides decentralization. TornadoCash is a best fit for individuals and businesses looking for financial freedom in the Ethereum ecosystem.
